BWFZJ-13K-4 shutdownMonitoring Device, Explosion-Proof RatingExdⅡBT6 ,Flame monitor for industrial burners using gas or oil, the monitor is specifically designed forFlameIt is sensitive to ultraviolet radiation but unresponsive to light and high-temperature radiation from furnaces, with strong anti-interference capabilities.

One,Feature Overview： 

Explosion-proof boxInstalledBWZJ-43-K UV Flame SwitchCircuit breakersSwitching Power Supply, IntermediateRelay、Buttons, indicators, and other control components. Inside the box.BWZJ-43-K UV Flame SwitchUtilizing our high-performance products, electrical components are sourced from domestic renowned brands to ensure reliable equipment operation. In the event of an unexpected shutdown during system operation,The system can also upload flame signals to the central control room's supervisory computer in the form of switch signals. In the event of an unexpected flame-out failure, the central control room issues commands to interlock control the gas quick-cut valve, ensuring the safe, stable, and reliable operation of the entire production process system.

Two,Installation and Wiring:

■  Detection ProbeInstallation（Special Notice）The BWZJ-43-K UV Flame Monitor is a non-contact flame detection sensor. When installing, please align the probe with the flame. The probe operates at a temperature of 80°C. When using on burners or other high-temperature equipment, the detection channel in front of the probe must be ventilated and cooled. The diameter of the detection channel must be not less than Φ18, and the installation thread of the probe is M20×1.5.。

■  Control box installation

Explosion-proofThe box structure is wall-mounted, featuring fourM10Install the bolts at an appropriate location on-site for the equipment.Avoid installation in areas exposed to high temperatures, severe vibrations, or impacts.

Please refer to the wiring diagram inside the control box for wiring instructions.

Note: The flame signal wire must not be routed in the same conduit as high current power lines; it should be installed separately. After installation and confirmation that the wiring is correct, power can be applied for operation.。
